To all whom it may concern: f

Be it known that I, ,learns T. ANDREW, a citizen or the United States, residing at Montgomery, in the 'county of Montgomery and State ot' Alabama, have invented certain new and useful improvements in Railway Safety Appliances; and l do hereby declare the following to be a full, clear, and exact descriptionr of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

rlhis invention relates to railway safety appliances, and has for its object to improve the invention disclosed in my priori` ltatent $111,222, issued November 23, 1909.,

To this end, the invention consists in the novel 'details of construction and combinations of parts more :tally hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification,

in which llike numerals refer te like parts in all the ure 1 is a"ongitudinal sectional view of the-truck of a locomotive, with my improvements attached thereto; Fig. 2' is a sectional detail view of certain ofthe portions shown in Fig. 1; and Fig. 3 is an elevational'view of a hanger for the safety from the truck.

1 indicates the traclr, 2 the wheels ot a locomotive, 3 the axles and 4 one of the side bars of the truck. On the axles 3 I provide inside of. the wheels2 at each end hangers 5, preferably of the general shape shown in Fig. 3. 'lhese hangers are provided with orifices 6 through which pass the axles 7 ot" the safety rollers 8, which are located slightly above track 1 as shown. Extending from end to end of the truck underneath the axles 3, is a continuous beam 10, which is provided with U-shaped supporting brackets 11, passing down underneath and around the axle 7. The hangers 5 are provided with cut-away places12 to accommodatethe brasses 13 and with cut-away places 14 to accommodate the lubricating portion ot the journal box. Passing underneath the views z-Fi 17 in the hangers, and which are secured in by the'bolts 18, as shown..- Upon talring ont .the bolts 18 and removing thev plates 16, the hangers 5 can be readily removed Connecting the hangers 5v is a bar ,21, which steadies and braces the same, and re'- sists any twisting or distorting strains. Between the axles 7 and the beam 10 are a iiumber of pressure blocks 22, which when the engine is derailed, and the strain is brought upon the rollers 8, serve to transmit the strain from the axles 7 to the beam 10, which in turn transmits said strain to the main axles 3 ot .the truck, as will be readily understood. ln the same way this strain is transmitted through the plates 16 and box 40 to the axles 3, as will be clear from Fig. 1.

The extreme forward and roar safety rollers 25zare provided with a conical bore 26, as illustrated in Fig. 2, and also with a circumferential groove 27, in which tits a segment of a ring 28, Fig. 1, attached to the spring-pressedV rod 29, controlling the air valve 30, and connected by the pipe 31 to the air-brake system.

The operation of my invention is as follows z-Asclearly disclosed in my former patent above, lwhen the engine leaves the track, the safety rollers on one side oit thc truck receive the weigl'it of the engine and truck on one rail, while wheels such as 35 on the other side of the engine receive the weight of said engine and tru ck on the other rail. ln the present invention, however, when the forward or rear rollers l25 come in contact with the rail, the said rollers will be lifted, owing to their conical boro, and will thereupon raise the spring-pressed rod 29, to operate the air valve 330, and to automatically apply thc brakes to thc train. ln all cases the weight which comes' upon the safety rollers 8 and is transmitted through the axles 7 to the longitudinal beams 10, which in. to the main axles 3 oi the truck. portion ot'. this strain is also transmitled through the plates 1G and box Ll() to the main axles 3, as above indicated.

It is obvious that those skilled in the art may vary the details of construction and the arrangement ol parts without departing from the spirit oiz my invention, and, there fore, l. do not wish to be limited to such eatures as disclosed, except as may be required by the claims.

The brake applying mechanism ot' this case is not claimed herein, but is made the subject of my divisional application eccome, slee Jan. a, 191i.

Tbination of atruck provided with main said axles; a plurality of safety axles under said beam; and connections through which strains may be transmitted from said safety i axles; a longitudinal beam extending under hangers axles to said beam and from said beam to main axles through which said safety axles pass; safety rollers on said safety axles; and connections through which strains may be transmitted from said safety axles to said beam and from said beam to said substantially as described.

ln a railway safety appliance the com bination of a' truck provided with main axles; hangers provided with recesses to accommodate portions of the journal boxes on said axles; safety axles supported from said hangers; and a longitudinal beam crossing said safety axles, substantially as described.

al, ln a railway safety appliance the com' bination of a truck provided With main axles; hangers provided with recesses to accommodate portions ofthe journal boxes on said axles; connections between each pair of safety axles supported from hangers; a longitudinal beam connected to said safety axles; and connections between said beam and safety axles adapted to trans;

init strains from the latter to the former;

substantially as described.

In a railway safety appliance the combination of a truck provided with main axles; hangers provided 1:'vith recesses to accommodate portions of the journal boxes on said axles; connections between said hangers; safety axles supported fromsaid hangers; a longitudinal -beam joining said safety axles, adapted'to contact with said main axles; connections between said safety axles and said beam adapted to transmit strains to and through said beam'to said main axles; and connections betw'pen the lower portion of said hangers and said main axles adapted to transmit strains from said safety axles to said main axles,'sub stantially as described. f y

In testimony Whereof,'I' aix` my 'signature, in presence of two Witnesses.
